Ok so you would advise to level my gems further before starting to work on Caldesann's? If you're having difficulties I'm guessing you're dying too much? The build is very squishy and you need to be extra careful after a proc because your minions will be gone. Damage is great but it needs a lot of dodging and alertness :-)

I'm a long time lurker here but now I could use some advice I've been working on my Rathma build: https://www.d3planner.com/665930806. Doing fine so far but now it seems my damage is lacking (finished GR 89, might do 90 but I guess not higher)

What would you guys focus on first? Caldesann's? And if so, what level would you recommend given my current status? Or is there something I'm overlooking that would help even more?
